Does K2Cr2O7 act as an oxidizing agent in an alkaline medium?

WebbOxidation process involves loss of electrons while reduction process involves gain of electrons. Thus an oxidizing agent is one which accepts electrons while a reducing agent is one which loses the electrons. An oxidizing agent oxidizes the other substance by stripping off electrons from it. Webb2- Oxidation reduction (Redox) titration Redox titrations are based on a reduction-oxidation reaction between an oxidizing agent and a reducing agent. A potentiometer or a redox indicator is usually used to determine the endpoint of the titration, as when one of the constituents is the oxidizing agent potassium dichromate.
